I was wondering if anyone could share their experiences with estimating populations on photos they've taken with UAVs. Software or particular methods that you have found to work. I currently use a Y6 tri-copter from Event 38 with a GoPro Camera as well as a Canon SX 260 converted to near-infrared. I've used Agisoft Photoscan with great success in photo-stitching and dronemapper. I've dabbled with Fiji/image j, and Microsoft ICE but I've found they seem to have more of a learning curve for me.
Any ideas if population estimates work well in any of these programs or in others that I have not mentioned?
